For a steady flow of charge through a surface, the current I in amperes can be calculated with the following equation:I = Q/t

where Q is the electric charge transferred through the surface over some time t. If Q and t are measured in coulombs and seconds respectively, I is in amperes.

Thus:

I = 0.24 coulombs / 15 msec

I = 0.24 coulombs / 15 * 10^-3 sec

I = 16 amps

Divide the coulombs by the amperes. The answer will be in seconds. The resistance is irrelevant in this problem.

Current must always be expressed in?

Current must always be expressed in amperes (A), which is the standard unit of measurement in the International System of Units (SI). It quantifies the flow of electric charge in a circuit, indicating how many coulombs pass a point in one second. Other units, such as milliamperes (mA) or microamperes (µA), are often used for convenience in specific contexts, but they are all based on the ampere.

What is the unit of current in which 6240000000000000000 electrons flow past a given point in a circuit in one second?

The formula for current is I = Q/t [A = C/s]. In words, current in amps is equal to charge in coulombs divided by time in seconds.In order to answer this question, you must first calculate the number of coulombs in the specified number of electrons.Q = (# of electrons) * (elementary charge) = 6.24x1018 * 1.602x10-19 = 0.999648 CThen substitute this value into the first equation using the given time:I = Q/t = 0.99648C / 1s = 0.999648 AIf one were to round to the nearest thousandth, this value would become approximately 1 Amp.Be aware that current moves in the opposite direction that electrons move, even though the rate is the same.
